phase(A relative measurement that describes the temporal relationship between two signals that have the same frequency. Phase is measured in degrees, with one full oscillation cycle having 360 degrees. The phase of one signal can lead or follow the other by 0 through 180 degrees); phase(A relative measurement that describes the temporal relationship between two signals that have the same frequency.

Adding stages to a workflow does not affect how the steps function. Stages are purely for conceptual grouping of steps within complex workflows)
